使用 Python 在批处理脚本中按下一个键

Question

I have a script in python that execute a batch program that need press two or three times the "d" key and after the "q" key.

I tried this but without solution:

import os
import keyboard
import time
from pynput.keyboard import Key, Controller

os.system('"C:/Users/xxx/Documents/Software/xxx.exe 192.168.0.15"')
time.sleep(5)

keyboard = Controller()
keyd = "d"
keyq = "q"

keyboard.press(keyd)
keyboard.release(keyd)
time.sleep(3)
keyboard.press(keyq)
keyboard.release(keyq)

Only open the console but the script don't press the keys, but if you press with the keyboard the program works fine.

Answer 1

You could try to use the subprocess module.

Example:

subprocess-test.py

import subprocess

p = subprocess.Popen(["python", "input-app.py"], stdin=subprocess.PIPE)

p.stdin.write("Hello\n".encode(encoding='UTF-8'))
p.stdin.write("World\n".encode(encoding='UTF-8'))

input-app.py

input1 = input("Input 1: ")
input2 = input("Input 2: ")

print(input1, input2)

Sorry, I won't be able to help more as I only have a short lunch break. I hope this already does help though or points you in the right direction!

You can use: pyautogui for pressing code as simply as:

import pyautogui
pyautogui.press('d')

Your case can be handled as follows:

import os
import pyautogui
import time

os.system('"C:/Users/xxx/Documents/Software/xxx.exe 192.168.0.15"')
time.sleep(5)

keyd = "d"
keyq = "q"

pyautogui.press(keyd)
time.sleep(3)
pyautogui.press(keyq)

If pressing keys don't work, you may try to enter exact strings as well:

import os
import pyautogui
import time

os.system('"C:/Users/xxx/Documents/Software/xxx.exe 192.168.0.15"')
time.sleep(5)

keyd = "d"
keyq = "q"

pyautogui.write(keyd)
time.sleep(3)
pyautogui.write(keyq)
